Specialty Resin for Ammonia Nitrogen Removal


KP-002 is a specialty wastewater treatment ion exchange resin synthesized with special technology, specializing in removing ammonia nitrogen ions. Owing to its uniform and solid structure and its low expansion rate after reversible ionic transformation, this resin performs with good anti-osmotic efficiency and excellent shock resistance. The mesh porosity of the resin does not vary from solution swelling, and it remains with good exchange and adsorption performance in organic solutions. It is primarily used in ammonia nitrogen removal in wastewater or industrial sewage treatment.
